SPECIFICATION forming part of Letters, meat No. 739,253, dated September 15,1903.

Application filed clatter s, 1902. Serial no. 125,749. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH BOIVIN, a citizen of the United States, residing in Paterson, in a the county of Passaic and State of New Jersey, have invented certain new and useful Improvementsin Drying,Lusterin g,and Stretching Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to the treatment of silk in skeins subsequently to the operation of dyeing, so as to impart luster to the silk.

' After the skeins have been taken from the dye-bath and freed of the greater portion of their m'oisture bya hydro-extractor or some other suitable means they are, according to one common and well-known method of treatment, stretched while still damp from the dyebath and while maintained stretched are sub-' jected to the drying effects of a-sufticientlyheated atmosphere. By thus stretching the skeins while still wet from the dye-bath and drying them while maintained stretched the silk is given a luster which is both perfect and permanent.

My invention consists in an improved apparatus for use in connection with the abovementioned process in stretching the skeins and maintaining them stretched during the drying step of said process. 3

My invention further consists in providing such an apparatus with automatic means whereby when a predetermined tension has been placed on the skeins the stretching action of the apparatus will be, ca used to cease.

which the apparatus is located, supports horizontal beams e and 'f, disposed the one above the other. 1 In bearings g, supported on the blocks 17, a're'stepped vertical screws it, said screws being journaled near their upper ends in bearing-blocks i, bolted to the beams; Each screw carries a series of pairs of cross-armsj and It, which it is the function of said screw to separate or bring together. "The middle portion of each cross-arm has bolted to it a strap Z,

while in the case of the cross-armj said bore m is smooth.

n, is a collar adapted to be adjustably fixed on the screw by a'set-screw 0 between the two cross-arms in each pair and which acts as a.

stop for the cross-army. In view of the fore going it will be seen that if the cross-arms are prevented from turning the rotating of the from or approach the other cross-arm in each pair, according to the direction in which the screw is turned. The tendency of the crossarms to turn with the screw is prevented by a vertical rod 1), which is preferably secured in the beams e and f'and the corresponding block 9 and which is held in place in a vertical recess q in each cross-arm by its strap Z.

The cross-arms'j and Yo'are" grooved longi-. 'tudinally in their outer edges, and in these These grooves are adapted to seat rods a". rods are preferably made of wood and serve to keep the skeins (marked 8) out of contact with 'thecross-arms, which for the sake ofstrength are preferably made of metal. As the rods 0" might become soiled by rust from the metallic cross-arms and damage the silk, I prefer to form these cross-arms, as shown at t in Fig. 5, with the portions thereof in which the rods directly seat,composed'of some non-oxidizable material, such as wood. 4

u is a horizontal shaft which is journaled in the support dand in a bearing-bracket 'u,

screw will cause the cross-arm k to move away ICO sustained by the beam s. This shaft is adapted to be rotated bya crank w, which is preferably connected with the shaft bya sprocketand-chain arrangement 00. The shaft to carries a series of bevel-gears g, which intermesh with other bevel-gears a, each surmounting one of the screws h. The upper end of each screw is reduced, as at 1, and receives a collar 2, which forms a bearing for the gear 2, said gear being recessed, as at 8, for the reception of said collar. To keep the gear down on the collar, a cotter-pin 4t and washer5 may be provided. (See Fig. 3.) The gear .2 is thus free to turn on the screw. On each screw below the corresponding gear a is keyed a clutch 6, which is formed with an annular groove 7, receiving a fork 8, which is fulcrumed on a bracket 9 on the beam e. Said clutch and the gear ,2 are formed with interlocking ratchet-teeth 10 on their adjacent faces,so that when the clutch is forced against the gear the rotary movement of the former will be imparted to the latter, and consequently to the screw. Each fork 8 is connected with the beamfby levers ll, which are connected at 12, so as to form a togglejoint. A stop 13 on one of them engages the other, so as to keep them end to end and alined; but it the joint is pushed against from the opposite side said levers will buckle, and

thusdraw the fork 8 downwardly. In order to actuate the levers, the cross-arm 7c in one of the pairs of cross-arms on the screw is provided with a lug 14:, which as it moves downwardly with the cross-arm is adapted to engage said levers at their joint. It of course depends upon the form of the lug 14 as to just when in the downward movement of the cross-arm which carries it the levers will be actuated by said lug. By the mechanism above described when the stretching operaation has proceeded to a predetermined extent it will be automatically stopped, the skeins being left to stand stretched at the degree of tension at which the increasing of the tension was stopped.

I do not wish to be limited to that embodiment of my invention herein particularly described and shown; but

What I do claim as new, and desire to secure by Letters Patent, is-

1. The combination of substantially parallel members adapted to receive the skeins to be operated upon and one of which is movable to and from the other, and a rotary part formed with an inclined surface whereby said movable member is controlled, substantially as described.

2. The combination of substantially parallel members adapted to receive the skeins to be operated upon and one of which is movable to and from the other, a screw penetrating said members and engaging with its threaded portion the movable member, and a collar disposed between said members and forming a stop for the other member, substantially as described.

3. The combination of substantially parallel members adapted to receive the skeins to be operated upon and one of which is movable to and from the other, ascrew penetrating said members and engaging with its threaded portion the movable member, a collar disposed between said members and forming a stop forthe other member, and means for securing said members against rotation with the screw, substantially as described.

4. The combination of a pair of members for receiving the skeins to be operated upon, one of said members being movable to and from the other, means for moving said movable member away from the other member, disconnective connecting mechanism between said movable member and its actuating means, and means forautomatically actuating said disconnective connecting means so as to disconnectsaid movable member from its actuating means, substantially as described.

5. The combination of a pair of members for receiving the skeins to be operated upon, one of said members being movable to and from the other, means for moving said movable member away from the other member, disconnective connecting means between said movable member and its actuating means, and means, controlled by said movable member, for actuating said disconnective con necting means, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 30th day of September, 1902.
